My therapist would always make a point to counsel me that life is not like books; in books no one has to go to the bathroom, etc.

Someone writing a book can make things smooth and look good. Think about conversations; it's highly unlikely that anyone is going to remember them word-for-word and there's all those silences and "um" stupid sounding stuff that gets taken out so you get this beautiful "speech" that has been tweaked, just like fashion models get air brushed! I would not compare myself to a book character, whether based on real life or not!
